LIQUID-DIRECTING DEVICE.

SPECIFICATION forming part of Letters latent No. 768,875, dated August 30, 1904:.

Application filed September 17, 1903. Serial No. 173,527. (No model.)

To all whom it may concern:

Be it known that we, WALTER H. BROWN, of East Boston, and JOHNE. TRUCKSES, of Charlestown, in the county of Suffolk and State of Massachusetts, have invented certain new and usefullmprovements in Liquid-Directing Devices, of which the following is a specification.

This invention relates to a liquid-directing device designed particularly for use in connection with apparatus for mixing air and a combustible gas in predetermined proportions and supplying the same under'pre'ssure for use in heating, lighting, &c., such as in our Patent No. 748,840, granted January 5, 1904.

The invention has for its object to provide a simple, durable, and effective device of this character; and it consists in the improvements which we will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figures 1 and 2 represent enlarged elevations, partly in section, illustrating our invention. Fig. 3 represents aside view of the cock-plug detached. Fig. 4 represents a section on line 4 4 of Fig. 3. Fig. 5 represents asection on line 5 5 of Fig. 3.

The same reference characters indicate the same parts in all the figures.

In the drawings, 70 represents a conduit, through which liquid is discharged by the liquid-directing device to apparatus such as shown in said patent. Said device comprises the casing m of a three-way cock, in which is a movable plug member a. The cock-casing m has three branches 2, 3, and 4. The branch 3 is double-acting or serves to conduct liquid from and to the casing and is connected with the conduit 70. The branch 2 conducts liquid to the casing from a supply-pipe o, communicating valve which alternately closes the branches 2 and 4, as hereinafter described. The offset grooves 92/ a are so formed and arranged that when the plug is at one extreme ofits movement the groove 11 coincides with the branches 2 and 3, as shown in Fig. 1, so that water from the supply-pipe 0 can pass through the cockcasing to the conduit is, the branch 4, leading to the waste-pipep, being at this time shut off from the branches 2 and 3 by the valve portion 02/ of the plug a.

n represents a groove or port formed in the upperend of the valve portion 12/ and arranged to connect the oflset groove a with the outlet branch 4 when the plug is in the position shown in Fig; 1. Provision is thus made for the escape to the waste-pipe of water that may find its way upwardly between the plug and easing, said water being thus prevented from escaping from the upper end of the casing.

'1' represents a weighted lever pivoted at r to a fixed support and having a segmental slot 7' in one of its arms, said slot receiving a pin a, connected with the stem of the plug a. The said lever has another arm, to which is pivotally connected the lower end of a vertical rod 8, which may be lifted to depress the plug a, as shown in Fig. 2, or depressed to cause a movement of the lever r in the direction required to raise the plug a, as shown in Fig. 1. hen the plug is depressed, its offset groove 11, is moved out of connection with the branches 2 and 3 of the cock-casing, and its ofiset groove a is brought into connection with the branches 4 and 3, as shown in Fig. 2. The inlet branch 2 is now closed by the Valve portion a of the periphery of the plug, and the branch 3 is connected, through the groove M, with the outlet branch 4 and the waste-pipep, so that the fluid which has been forced through the conduit 70 into a suitable receiver or cylinder ,rnay return and escape therefore enables the lever to swing past its vertical position and begin to swing downwardly by gravitation before moving the plug, so that the plug is moved quickly in each direction by the momentum of the fallin g weight,

To permit the plug 'n to move freely to its lowest position (shown in Fig. 2) without being obstructed by the water below it, we provide a passage 25, connecting the lower portion of the plug-chamber in the casing m with the outlet branch 4:, so that as the plug descends it forces the water below it out through the passage 1. A liquid-directing device comprising a three-way-cock casing adapted to be connected with a conduit and having an inlet adapted to be connected with a source of supply of fluid-under pressure, and having also an outlet; a cock-plug movable longitudinally in said casing and having two ofl'set peripheral grooves separated at one side of the plug by an elongated valve portion; said grooves be ing formed to connect the conduit alternately with the said inlet and outlet.

2. A liquid-directing device comprising a thrce-way-cock casing having at one side an inlet branch and an outlet branch, and at the opposite side a double-acting branch serving both as an inlet and an outlet, and a cock-plug longitudinally movable in said casing and having two otl'set peripheral grooves separated at one side of the plug by an elongated valve portion adapted to cover the inlet and the outlet branch alternately.

3. A liquid-directing device comprising a three-way-cock easing having at one side an inlet branch and an outlet branch, and at the opposite side a double-acting branch serving both as aninlet and an outlet, and a cock-plug longitudinally movable in said casing and having two offset peripheral grooves separated at one side of the plug by an elongated valve portion adapted to cover the inlet and the outlet branch alternately, the casing having a passage connecting its inner end with the outlet branch.

4. A liquid-directing device comprising a three-way-cock casing having at one side an inlet branch and an outlet branch, and at the opposite side a double-acting branch serving both as an inlet and an outlet, and a cock-plug longitudinally movable in said casing and having two offset peripheral grooves separated at one side of the plug by an elongated valve portion adapted to cover the inlet and the outlet branch alternately, the valve portion of the plug having a groove arranged to connect one of the oifset grooves with the outlet branch.

In testimony whereof we have affixed our signatures in presence of two witnesses.
